Here come the questions

  • What color is the exhaust smoke?
  • Do you use fuel additive(s)?
  • Why the PCV? Is it needed (excessive blowby)?
  • If your first plugs showed a rich mixture, why richen the mixture further with the new carburetor (turning the mixture screw in richens the mix)?
  • Is a precise timing exercise possible (as opposed to timing by feel)? By possible I mean do you have the means/tooling to precisely find #1 TDC, i.e., MMI crankshaft timing tool or precision measuring equipment, timing light. Do you have the means to make a precise timing mark (as opposed to the crankshaft roll pin)?
